Windows Question

What is the best way to stop mould forming on the inside of window frames?

We live in a ~1950s house and have mould forming around the inside of our windows. I know its to do with a lack of ventilation. We keep applying bleach to get rid of the mould but wondered if we need new windows or will it always keep happening?

Hi
What you need are trickle vents fitted in the windows
These are the open and shut vents you see at the top of windows
These will ventilate all the windows and stop the condensation forming which in turn causes the mould to form
Hope this helps

Your right with the ventilation. Also it depends if the right sealants have been used.

As above ventilation is definately required, what material are the frames made from? wood? metal? ventilation will help and the right sealents,however if there is an underlying problem in the integrity of the frame (rot, holes)the problem will return and keep returning, check the frames for any sign of rot/holes, also check above the frame, is there damp there? any moisture from above? Bleach will eventually damage the seal.

Had the same problems on my house all the window frames were very old.
